Table 13 Habila: GAM point estimates, 95% CIs, LQAS result and estimated time expenditure* for data collection, by sampling design

From: Precision, time, and cost: a comparison of three sampling designs in an emergency setting

Sampling design GAM point estimate (95% CI) GAM LQAS result Team days required to collect data Cost for data collection
33 × 6 Design 4.7 (1.9, 7.4) Reject Ho at 10% GAM threshold.
Conclude area has <10% GAM prevalence
4.13 NA
67 × 3 Design 8.0 (4.5, 11.5) Fail to reject Ho at 10% GAM threshold.
Conclude area requires intervention appropriate for 10% threshold level
5.58 NA
30 × 30 Design 6.9 (4.8, 9.0) NA 15.00 NA
  1. *Time expenditure results for Habila assume 12 hour work day.
